While looking for a very specific song (that electro song from Marisha's teaser for Creator Clash 2), Shazam led me to Volta Music, a label promoted by Universal. Digging deeper I've found that some of the music used by CR is from Universal Promotion Music (for instance here's the song used at the end of "Crafting a Mystery with Spenser Starke" video ; here's the song used for CR's shop bit). While I'm not certain that CR always uses music from Universal (besides their own; and more specifically when they play), I guess they use their services (since CR left Geek & Sundry?).
My point is not to track down every song CR uses ([or not all by myself, at least] that'd be exhausting and probably not very useful), but to hint that some of the music comes from Universal. Where do you think this information would be relevant, if it were?
